Overview

This is the puppetboard puppet module.

Puppetboard is an open source puppet dashboard

https://github.com/voxpupuli/puppetboard

Setup

Installation

puppet module install puppet-puppetboard

Dependencies

Note that this module no longer explicitly requires the puppetlabs apache module. If you want to use the apache functionality of this module you will have to specify that the apache module is installed with:

puppet module install puppetlabs-apache

This module also requires the git and virtualenv packages. These can be enabled in the module by:

class { 'puppetboard':
  manage_git        => true,
  manage_virtualenv => true,
}

or by:

class { 'puppetboard':
  manage_git        => 'latest',
  manage_virtualenv => 'latest',
}

If the virtualenv is managed by this module, the voxpupuli/python will be used. That module uses voxpupuli/epel on RHEL based platforms.

Usage

Declare the base puppetboard manifest:

class { 'puppetboard': }

Number of Reports

NOTE: In order to have reports present in the dashboard, report storage must be enabled on the Puppet master node. This is not the default behavior, so it mush be enabled.

See https://docs.puppet.com/puppetdb/latest/connect_puppet_master.html#enabling-report-storage for instructions on report storage.

By default, puppetboard displays only 10 reports. This number can be controlled to set the number of reports to show.

class { 'puppetboard':
  reports_count => 40
}

Offline Mode

If you are running puppetboard in an environment which does not have network access to public CDNs, puppet board can load static assets (jquery, semantic-ui, tablesorter, etc) from the local web server instead of a CDN:

class { 'puppetboard':
  offline_mode => true,
}

Set Default Environment

by default, puppetboard defaults to "production" environment. This can be set to default to a different environment.

class { 'puppetboard':
  default_environment => 'customers',
}

or to default to "All environments":

class { 'puppetboard':
  default_environment => '*',
}

Disable SELinux

class { 'puppetboard':
  manage_selinux => false,
}

Apache

If you want puppetboard accessible through Apache and you're able to use the official puppetlabs/apache Puppet module, this module contains two classes to help configuration.

The first, puppetboard::apache::vhost, will use the apache::vhost defined-type to create a full virtual host. This is useful if you want puppetboard to be available from http://pboard.example.com:

(The following is generic code used in our tests, it works on Debian 9 and 10, also on Ubuntu 16.04 and 18.04. It will talk to PuppetDB on localhost via http)

# Configure Apache on this server
class { 'apache':
  default_vhost => false,
  purge_configs => true,
}
$wsgi = $facts['os']['family'] ? {
  'Debian' => {package_name => "libapache2-mod-wsgi-py3", mod_path => "/usr/lib/apache2/modules/mod_wsgi.so"},
  default  => {},
}
class { 'apache::mod::wsgi':
  * => $wsgi,
}

# Configure Puppetboard
class { 'puppetboard':
  manage_virtualenv => true,
  manage_git        => true,
  require           => Class['puppetdb'],
}

# Access Puppetboard through pboard.example.com
class { 'puppetboard::apache::vhost':
  vhost_name => 'localhost',
  port       => 80,
}

The second, puppetboard::apache::conf, will create an entry in /etc/apache2/conf.d (or /etc/httpd/conf.d, depending on your distribution). This is useful if you simply want puppetboard accessible from http://example.com/puppetboard:

# Configure Apache
# Ensure it does *not* purge configuration files
class { 'apache':
  purge_configs => false,
  mpm_module    => 'prefork',
  default_vhost => true,
  default_mods  => false,
}

class { 'apache::mod::wsgi': }

# Configure Puppetboard
class { 'puppetboard': }

# Access Puppetboard from example.com/puppetboard
class { 'puppetboard::apache::conf': }

Apache (with Reverse Proxy)

You can also relocate puppetboard to a sub-URI of a Virtual Host. This is useful if you want to reverse-proxy puppetboard, but are not planning on dedicating a domain just for puppetboard:

class { 'puppetboard::apache::vhost':
  vhost_name => 'dashes.acme',
  wsgi_alias => '/pboard',
}

In this case puppetboard will be available (on the default) on http://dashes.acme:5000/pboard. You can then reverse-proxy to it like so:

Redirect /pboard /pboard/
ProxyPass /pboard/ http://dashes.acme:5000/pboard/
ProxyPassReverse /pboard/ http://dashes.acme:5000/pboard/

Using the puppetlabs/apache module:

apache::vhost { 'example.acme':
  port            => '80',
  docroot         => '/var/www/html',
  redirect_source => [ '/pboard' ],
  redirect_dest   => [ '/pboard/' ],
  proxy_pass      => [
    {
      'path' => '/pboard/',
      'url'  => 'http://dashes.acme:5000/pboard/',
    },
  ],
}

RedHat/CentOS 7 with Python 3

CentOS/RedHat 7 is pretty old. Python 3 got added after the initial release and a lot of packages are missing. For example python3.6 is available as a package, but no matching wsgi module for apache is available. Because of that, we don't test on CentOS 7 anymore. However, it's still possible to setup Puppetboard on CentOS with gunicorn as a webserver and nginx/apache forwarding to it.

Using SSL to the PuppetDB host

If you would like to use certificate auth into the PuppetDB service you must configure puppetboard to use a client certificate and private key.

You have two options for the source of the client certificate & key:

1. Generate a new certificate, signed by the puppetmaster CA
2. Use the existing puppet client certificate

If you choose option 1, generate the new certificates on the CA puppet master as follows:

sudo puppet cert generate puppetboard.example.com

Note: this name cannot conflict with an existing certificate name.

The new certificate and private key can be found in $certdir/.pem and $privatekeydir/.pem on the CA puppet master. If you are not running puppetboard on the CA puppet master you will need to copy the certificate and key to the node running puppetboard.

Here's an example, using new certificates:

$ssl_dir = '/var/lib/puppetboard/ssl'
$puppetboard_certname = 'puppetboard.example.com'
class { 'puppetboard':
  manage_virtualenv   => true,
  puppetdb_host       => 'puppetdb.example.com',
  puppetdb_port       => 8081,
  puppetdb_key        => "${ssl_dir}/private_keys/${puppetboard_certname}.pem",
  puppetdb_ssl_verify => "${ssl_dir}/certs/ca.pem",
  puppetdb_cert       => "${ssl_dir}/certs/${puppetboard_certname}.pem",
}

If you are re-using the existing puppet client certificates, they will already exist on the node (assuming puppet has been run and the client cert signed by the puppet master). However, the puppetboaard user will not have permission to read the private key unless you add it to the puppet group.

Here's a complete example, re-using the puppet client certs:

$ssl_dir = $::settings::ssldir
$puppetboard_certname = $::certname
class { 'puppetboard':
  groups              => 'puppet',
  manage_virtualenv   => true,
  puppetdb_host       => 'puppetdb.example.com',
  puppetdb_port       => 8081,
  puppetdb_key        => "${ssl_dir}/private_keys/${puppetboard_certname}.pem",
  puppetdb_ssl_verify => "${ssl_dir}/certs/ca.pem",
  puppetdb_cert       => "${ssl_dir}/certs/${puppetboard_certname}.pem",
}

Note that both the above approaches only work if you have the Puppet CA root certificate added to the root certificate authority file used by your operating system. If you want to specify the location to the Puppet CA file ( you probably do) you have to use the syntax below. Currently this is a bit of a gross hack, but it's an open issue to resolve it in the Puppet module:

$ssl_dir = $::settings::ssldir
$puppetboard_certname = $::certname
class { 'puppetboard':
  groups              => 'puppet',
  manage_virtualenv   => true,
  puppetdb_host       => 'puppetdb.example.com',
  puppetdb_port       => 8081,
  puppetdb_key        => "${ssl_dir}/private_keys/${puppetboard_certname}.pem",
  puppetdb_ssl_verify => "${ssl_dir}/certs/ca.pem",
  puppetdb_cert       => "${ssl_dir}/certs/${puppetboard_certname}.pem",
}

Using SSL to PuppetDB >= 6.9.1

As of PuppetDB 6.9.1 the /metrics/v2 API is only accessible on the loopback/localhost interface of the PuppetDB server. This requires you to run puppetboard locally on that host and configure puppetdb_host to 127.0.0.1:

$ssl_dir = $::settings::ssldir
$puppetboard_certname = $::certname
class { 'puppetboard':
  groups              => 'puppet',
  manage_virtualenv   => true,
  puppetdb_host       => '127.0.0.1',
  puppetdb_port       => 8081,
  puppetdb_key        => "${ssl_dir}/private_keys/${puppetboard_certname}.pem",
  puppetdb_ssl_verify => "${ssl_dir}/certs/ca.pem",
  puppetdb_cert       => "${ssl_dir}/certs/${puppetboard_certname}.pem",
}

NOTE In order for SSL to verify properly in this setup, you'll need your Puppet SSL certificate to have an IP Subject Alternative Name setup for 127.0.0.1, otherwise the certificate verification will fail. You can set this up in your puppet.conf with the dns_alt_names configuration option, documented here.

[main]
    dns_alt_names = puppetdb,puppetdb.domain.tld,puppetboard,puppetboard.domain.tld,IP:127.0.0.1

NOTE If you need to regenerate your existing cert to add DNS Alt Names follow the documentation here:

# remove the existing agent certs
puppetserver ca clean --certname <CERTNAME_OF_YOUR_PUPPETDB>
puppet ssl clean

# stop our services
puppet resource service puppetserver ensure=stopped
puppet resource service puppetdb ensure=stopped

# regenerate our cert
puppetserver ca generate --certname <CERTNAME> --subject-alt-names puppetdb,puppetdb.domain.tld,puppetboard,puppetboard.domain.tld,IP:127.0.0.1 --ca-client
# copy the cert into the PuppetDB directory
cp /etc/puppetlabs/puppet/ssl/certs/<CERTNAME>.pem /etc/puppetlabs/puppetdb/ssl/public.pem
cp /etc/puppetlabs/puppet/ssl/private_keys/<CERTNAME>.pem /etc/puppetlabs/puppetdb/ssl/private.pem

# restart our services
puppet resource service puppetdb ensure=running
puppet resource service puppetserver ensure=running
